Public bug reported:

This is part of the master bug 824099

When connecting an external monitor, external screen is entirely black,
except for the top panel, and the built-in display shows a "dead zone"
on the top fourth of the screen, while the bottom 3/4ths are alive and
well. I'm attaching a screenshot of the internal display of an affected
Intel machine.
